I wanted an inexpensive printer that I could enclose and this looked like a good option. I have had the printer a couple of weeks now and so far it has worked better than I expected. I actually pre-ordered it so it took about 3 weeks to get from China. I thought that it was easy to assemble after watching the video once. There are a few differences from the video, but it is close enough. The only problem that I had, was that the Y motor was wired backwards, after switching the wires, everything worked properly. The test prints looked respectable right out of the box. I also printed the parts for the charcoal and HEPA air filter on it which turned out really nice, and fit perfectly. PLA Sticks like crazy to the coating on the bed which is flat on my unit. I am curious to see how long the coating lasts.I am enclosing pictures of the 4s with the enclosure and air filter on it. I have not printed ABS yet, but I am hopeful of the results.I would recommend the Ghost 4s and would buy it again…
